Open Topic on Global Warming

Melting Icebergs Activity - September 19 - September 23, 2016

Melting Icebergs: Science Inquiry - The presented melting iceberg experiment is a great activity to present students with an inquiry of the effects of such events. This task is structured and contains the necessary guidance as to permit students construct and formulate their own questions as to understand the reality and seriousness of this melting of icebergs and polar ice caps. The experiment demonstrates that as the floating ice melts the volume of water increases. 

What would happen if the polar ice caps melted? There will be a combination of events: 1) rising of sea levels, 2) accelerate global warming, 3) changes ecosystems, 4) threatens human culture and economics, and 5) increases seawater freshwater contamination, which can affect coastal erosion. All these in one way or the other are interconnected. One of the most talked about concerns is that of the rising of the sea levels. It has been documented that the melting itself of icebergs doesn’t affect sea levels by itself. On the other end, the melting of the polar ice caps will because as the ice melts, the temperature of the seawater increases.

It is important to mention that the polar ice caps help reflect sunlight back into the atmosphere.  If the ice is melted, the sunlight will be absorbed by the ocean thus increasing the temperature which will cause the water to expand and rise.  This rising of the temperature will accelerate global warming.  Global warming has been a topic of national and global importance among communities of scientists and political officials.  This itself can bring other questions (inquiry) for this activity: A. How does global warming affect the polar ice caps? B. Have governmental agencies develop a realistic plan to slow down global warming (* In the past 100 years global warming has increase 1/2 degree)?  C. Currently, are the two mayor ice caps in danger (Artic & Artarctic)?  D.  How will it directly affect populations of humans and other species?  

All these questions can have its instructional value during this task. The great part of these types of activities is that it invites students to formulate their own inquiries and look for the answers. Definitely, this is a good inquiry based instruction sample in which active learning is in place. Students will engage in the activity by formulating questions and collecting data, which they will use to present and reflect. Students will conduct the experiment (given handout 'Melting Iceberg Experiment') and apply their learning to their lives, society, and technology (Hammerman, 2006).

The Hunts Point Middle School -MS 424.          

I would like to welcome all 8th and 7th grade science students to our classroom blog.  This is going to be an exciting year in science and the science blog is just one of the many tools we will have to help us understand the nature of science and how scientist think.  I will be posting every Monday our weekly science topics.  Your assignments as explained in class is to comment each topic I post and comment one of your classmate's comment.  You will have until Sunday at 5:00 PM to complete your assignment in order to get graded.

Instructions for this week September 13 to September 18, 2016:  Reply to this message by saying hello, put your name and class number.  Example " Hello everyone, this is George W. from class 820".

VIEWS OF EARTH: Formation of our Planet Theories

There are many theories that are designed to explain the phenomenon of how EARTH was formed.  Not all of these theories have the same support from the scientific community.  Please research various of these theories, select one and in two concise paragraphs describe and explain why you selected this theory as one of your favorite.  Present evidence and the resource (references) where you obtained the information.

The Life of the Red Blood Cell

Write a 2-3 paragraph description of what would it be like to be a RED BLOOD CELL in the human body.  If you were a RED BLOOD CELL, what would your day look like? What tasks would you have to accomplish? What would be your travel plans? Describe the entire flow of a RED BLOOD CELL within the circulatory system.  Remember to trace the flow through the heart, lungs, arteries, capillaries, and veins. View the following video clips to help you (press the following links):  VIDEO CLIP 1, VIDEO CLIP 2, VIDEO CLIP 3, and VIDEO CLIP 4.  Take notes as you view the short video clips and use any other resource.  Important: Remember to list your resources in your post.

Cell - The Basic Unit of Life -- Blog 4

Everything that is alive starts with a single cell. Cells have a life cycle - they grow (G1), they synthesize and dublicate its chromosomos (S), continue growing and getS ready for division (G2), and finally enterS mitosis (cell division). Visite the following link and play the THE CONTROL OF THE CELL CYCLE GAME. As you play the game take notes and summarize each mayor cell activity that is happening. Write a 3 paragraph summary. Be sure to answer the following in your summary: Analyze the life cycle of cells, explain cellular division, and the cell event that can cause a tumor (cancer). Important: Take notes while you play the cell cycle game and use these notes to help you write your comment. PLEASE CHECK YOUR SPELLING.

Open Topic: What Would Happen to Our Planet if Sea Levels Rise in the Next 100 Years? Week 3 (Oct. 27 - Nov. 4, 2013)

What Will Happen to Our Planet if Sea Levels Rises Feet by Feet? What will happen if polar ice caps melted? It will not be a surprise to see that sea levels could rise 3 feet (1 meter) in the next 100 years due to Global Warming. Some scientist estimate it can be up to 6 feet. TASK: Provide in your own words a brief essay (3 - 4 paragraphs)covering the following topic: 1. What will be the humanitarian impact if sea levels rise as predicted and the new World Map would looks as following (compare this World map with current map):
What would happen to people? Where will they go? How will our society absorb this impact? We as humans will always strive to survive events like these, but at a cost to society, the environment, and the human specie. Remember to provide evidence and the resources used to complete your task. Suggested resources - Please view before you post your work (video clips): What will happen if polar ice caps melted? (press link to watch video clip) and the following video clip Earth Under Water Important note: Antharthic and Greenland account for 90 % of the ice on Earth. If both were to melt, sea level water would rise approximately 230 feet.

Science and technology - Week 2 - October 7 thru October 14, 2013

In the early 1900's, many of today's known diseases were present but had different names and of cause, different treatments. Without today's technology, many of these diseases were: 1) undetectable, 2) not comprehended, 3) thought as 'not curable', or 4) simple left to chances. Example: Children with Down Syndrome were in the early 1900's institutionalized, as many other genetic disorders and disease state. Patients probably with cancer or tumors were treated without hope. A simple cold or bronchitis would complicate into a pneumonia maybe leading to death. Science was present, but medicine didn't flourish until technology began to change our lives. Today thanks to major advances in medicine due to technology lives are being saved everyday. Science, medicine, and technology will continue to change the lives of millions. YOUR TASK: Doing research, name one or two of the major advances done in medicine and working with new treatments that technology has had a major influence in. State the disease, the description of the disease , the technology, and how has it been used to fight the disease state. Cite your sources.
